Abstract

A testing instrument for camera lenses is described which automatically measures transfer functions and line spread functions provided the focusing plane is maintained. The frequency covers a continuous range of 0 lines/mm to 150 lines/mm. The gauging to 1 with 0 lines/mm of the transfer function is automatic under all f stop, color, and defocusing conditions. The misalignment caused by instrumentation and the measuring principle is compensated by a function potentiometer. The instrument described allows focusing to infinity by collimators and focusing up to 6 m without collimators. Evaluated and measured curves are compared.
